There are two different yet similar reports of strange green-skinned children found abandoned near villages in Europe. The first account dates back to the 12th century near Suffolk, England.
Local farmers found a boy and a girl weeping in a field. They brought the children to the home of Sir Richard de Calne in the village of Woolpit.
The children spoke no English and refused to eat food. They both wore oddly-colored clothing of unknown materials. Eventually they began to eat beans exclusively after going without food for several days, but only after they were shown how to open the stalks.
Both children were soon baptised. The boy grew weak shortly after and eventually died. The girl survived, learned to speak English, and ate other food. Her skin turned to a normal color.
When asked about her origins, the girl described a place with no sun where all the inhabitants were of green color. She claimed that she and the boy were separated from their people as they wandered in a large cavern and, upon exiting, were "struck sensless by the excessive light of the sun and the unusual temperature of the air." A separate recorded account states that the girl said she came from a place called St. Martin's Land where the people were all Christian.
Despite the bizarre accounts of the children's origins, some suggest that the children were lost and had wandered from the nearby village of Fordham St. Martin. Malnourishment gave their skin a greenish color.
The second account of green children comes from Banjos, Spain in August of 1887. A boy and a girl of greenish color were found abandoned near a cave. They did not speak Spanish and wore unfamiliar clothing. Their eyes were described as Oriental in appearance.
As with the first account from England, both children refused to eat at first. The boy grew weak and died, but the girl survived, learned Spanish, and explained that she and her companion came from a sunless land. This account differs from the first account as the girl was reported to have claimed they had been caught up in a whirlwind and found themselves in the cave. The girl died in 1892.
Neither of these reports describe any other strange activity in the area such as UFOs. The children's true origins were never discovered. While some suggest the green children were aliens from another world or dimension, the rational explanation would be that the children were lost and undernourished. In any case, these events still remain a mystery. What is odd is that both accounts, although happening hundreds of years apart, are strikingly similar. Perhaps they are a retelling of the same story.
